Solution Overview

Problem

Current cleaning methods for textile machines in the spinning industry are inefficient, with pneumatic blowing failing to remove 100% of fiber waste and vacuuming being hindered by reduced negative pressure, leading to inadequate cleaning and unnecessary dirt deposition in critical areas.

Innovation Solution

A cleaning device equipped with a pressure booster and suction tube that generates higher negative pressure, allowing for efficient removal of dust and fibers directly through the spinning mill's suction channel, eliminating the need for filter changes and enabling use across various machines with simple handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If pneumatic blowing with compressed air is used for cleaning, then cleaning speed is improved, but cleaning completeness deteriorates (100% of fiber waste cannot be removed)

Engineering Contradiction:
Improvecleaning speedVSAvoidcleaning completeness
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The invention uses a vacuum cleaner with a suction nozzle that generates negative pressure to remove fiber waste, replacing the conventional pneumatic blowing method. The suction nozzle is designed to create a vacuum effect that draws out fiber deposits from the spinning preparation machine, achieving both high cleaning speed and complete removal of fiber waste without blowing dirt into unintended areas.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Reliability

If vacuuming with machine suction is used for cleaning, then cleaning effectiveness is improved, but available vacuum pressure deteriorates (reduced to 300-500 Pa)

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidvacuum pressure
Core Design Contradiction:
ReliabilityVSStress or pressure

Solution Approach 1:

The vacuum cleaner is designed to be self-sufficient with its own suction source, independent of the spinning mill's central suction system. This allows the vacuum cleaner to generate its own negative pressure (approx. 3000 Pa), eliminating dependence on the weakened machine suction system and enabling thorough cleaning without being constrained by the reduced 300-500 Pa pressure available from the spinning mill's suction network.

Inventive Principle:
Principle #25Self-service

3Reliability

If industrial vacuum cleaners with high negative pressure are used for cleaning, then cleaning effectiveness is improved, but device complexity and handling difficulty deteriorate (large filter bags and heavy vacuum cleaner)

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidhandling ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The suction nozzle is designed with a compact, focused structure that concentrates the vacuum effect at the cleaning point. This localized design allows the vacuum cleaner to achieve high cleaning effectiveness with a smaller, more maneuverable body compared to conventional industrial vacuum cleaners with large filter bags, significantly improving handling ease while maintaining approx. 3000 Pa negative pressure for thorough cleaning.

Inventive Principle:
Principle #3Local quality

4Device complexity

If compressed air blowing is used for cleaning, then equipment simplicity is maintained, but harmful effects increase (fiber waste blown into nips and unintended openings)

Engineering Contradiction:
Improveequipment simplicityVSAvoiddirt deposition in critical areas
Core Design Contradiction:
Device complexityVSObject-generated harmful factors

Solution Approach 1:

Instead of blowing compressed air to remove fiber waste, the invention inverts the approach by using suction to draw out the contaminants. The vacuum cleaner's suction nozzle creates negative pressure that actively pulls fiber deposits from the spinning preparation machine into the collection container, preventing fiber waste from being blown into nips, bearings, and other unintended areas while maintaining equipment simplicity.

Inventive Principle:
Principle #13The other way round (Inversion)
